CMOS PCB-integrated multi-chip±4g piezoresistive accelerometer sensor comprising a
coupled multi-bandwidth variable-gain amplifier block and a thermal sensitivity and offset
compensation block is presented in this work. Custom design and fabrication has been
carried out for both the SOI MEMS sensor and the analog front-end for high precision and
operational reliability. The system is shown to have a scale factor of∼ 4 mV/g and an output …
